Shortly before the In the ex mpthe Separator comprises a separator 5, I has reached the saidintermediate spindle I (Fig. 13) which is provided with a position, anaxial movement of the spindle l selector wing 2 and two lateral lugs ordisis initiated in the direction of the arrow shown patchers 3 and 4 onits end face. The spindle I in Fig. 4, the thread a1 passing closely bythe tips traverses a guide sleeve 5 which is mounted ro of the tworetaining elements I and 8 (Fig.3). tatably on a carriage or slide (notshown). The Upon further axial movement of spindle l, the latter isguided in known manner on rails which said thread is moved away from thenon-seprun transversely above the warp. The said slide arated threads bymeans of the wing 2, as shown in Fig. 4, in which the spindle I hascovered part of its axial travel. When, subsequently, the separator 5, Ihas arrived in its second terminal position (Fig. 5), the separatedthread 411 (Fig. 6) has been removed a considerable distance from thenon-separated threads. When the separator 5, l rocks from the positionof Fig. 3 into that of Fig. 5, the retaining element 1 has arrived inthe path between the separated threads (11 and the non-separatedthreads. The separator 5, I then first remains in its angular positionshown in Fig. 5,, but the spindle .I is drawn axially into the guidesleeve 51 so as to arrive in the position shown in Fig. 8, the wing 2releasing the thread b1, whereupon thewin'g sleeve for the furtheroperating element, said 2 exerts a pressure onto the non-divided threadsG2, 122, as and so on. The separator 5, I then is rocked back into itsinitial position, the expelling movement of wing 2 having alreadly beeninitiated in the intermediate position shown in Figs. 9 and-10, and thethread in thereby 'having been removed from the non-separated threads.Shortly afterward the dispatching lug 4 engages the first separatedthread :11, owing to the axial movement of spindle I and to the rotarymovement of the latter along with the guide, sleeve '5, and moves thesaid thread through an additional distance in the'direction ofseparation, as may be seen in Figs. 11 and 12. In Fig. '11, theseparator has returned into the initial or startingposition of itsrocking movement. As-soon as the spindle I has returned from the axialposition of Fig. 12 to that of Fig. 2, the separator 5, I has resumedits initial position as shown in Figs. 1 and 2, whereupon the cycle isrepeated by separating the thread as and so on. What I claim as new anddesire to secure by Letters Patent is:

1. In apparatus, threads of the type having two lease rods for groupingthewarp thread rockably about an axis parallel to the lease rods andoutside the lease, the improvement comprising the provision of arockable shaft located outside the crossing of the threads and extendingparallel to the lease rods, said rockable shaft having a firstoperating-element and also a further operating element, said furtheroperating element being confor separating leased warp nected with thefirst operating element to turn 50 further element having a spindlewhich passes through said sleeve axially, and means connecting saidspindle withsaid sleeve for rotational driving, said sleeve having tworetaining devices standing opposite each other for the thread group.

3. In an apparatus for separating leased warp threads, the improvementset out in claim 2, in

1 which the two retaining devices are formed as plane surfaces.

threads, the improvements set out in claim 3, in which the spindle hastwo forward lateral arms for displacing the separated warp thread.

5. In an apparatus for separating leased warp threads, the improvementsset out in claim 1, in which the separator element is a spindle havingmeans for separating the threads and moving the separated threads awayfrom the warp, said spindle having two lateral lugs acting asdispatchers for the previously separated thread when displacing afreshly separated thread.

6. In an apparatus for separating leased warp threads, the improvementset out in claim 1, in which the separator element is a spindle havingmeans for separating the threads and moving the separated threads awayfrom the warp, a guide sleeve for transmitting rocking move ment to thespindle, said spindle traversing the guide sleeve.
